Origin of reduced dynamical friction by dark matter halos with net prograde rotation
Rimpei Chiba, Sandeep Kumar Kataria
We provide an explanation for the reduced dynamical friction on galactic bars in spinning dark matter halos. Earlier work based on linear theory predicted an increase in dynamical…
Dynamical friction and feedback on galactic bars in the general fast-slow regime
Rimpei Chiba
Current theories of dynamical friction on galactic bars are based either on linear perturbation theory, which is valid only in the fast limit where the bar changes its pattern spee…
Oscillating dynamical friction on galactic bars by trapped dark matter
Rimpei Chiba, Ralph Schönrich
The dynamic evolution of galactic bars in standard CDM models is dominated by angular momentum loss to the dark matter haloes via dynamical friction. Traditional approximations…
Tree-ring structure of Galactic bar resonance
Rimpei Chiba, Ralph Schönrich
Galaxy models have long predicted that galactic bars slow down by losing angular momentum to their postulated dark haloes. When the bar slows down, resonance sweeps radially outwar…
Resonance sweeping by a decelerating Galactic bar
Rimpei Chiba, Jennifer K. S. Friske, Ralph Schönrich
We provide the first quantitative evidence for the deceleration of the Galactic bar from local stellar kinematics in agreement with dynamical friction by a typical dark matter halo…
